If you want to spawn X-TREME in sandbox with a healtbar and not triggering Science’s Downfall, spawn a friendly treasure seller to sell X-TREME, kill the treasure seller then resummon X-TREME. This also works with Cross without triggering the background transition when Chronos spawns
i feel like mr mancer and infernus were the only ones that did a noticeable chunk of superbuffed infernus and that crusher was the only one to get him to the 2nd phase if you dont count chronos
